I just upgraded my 3 year old computer (Core 2 Duo to Athlon II), but I intend to keep my original hard disk. I have two OS on the HDD, Windows 7 and Ubuntu 10.04. After inserting the hard disk to the new computer, Ubuntu works just fine, but Windows does not even start. I guess it's driver issues.

What can I do to address the problem?

You can't easily use an old Windows 7 disk in a new computer.

Apart from the problem of drivers, you will also need to re-activate Windows, as too much hardware will have changed. And as your serial number is already taken for the old computer, you will have to beg Microsoft on the phone for a new serial. And if your current serial is OEM, then you can forget the whole thing right now.

You will need to reinstall Windows. See How to Run a Startup Repair in Windows 7 for how to do that in a way that preserves the existing applications.

Just remember that once that is done, you will find yourself starting the Windows trial period. I just hope that as in your case this is an old installation, Windows might not decide that the trial period is over and lock you out until you can supply a new serial.

+1 for correct answer... but I think it's funny every time I hear how people have to "beg" to get the serial number transferred over -- all they do is ask on how many machines the serial is being used, and that's it. It's even all automated now. –  Billy ONeal Oct 9 '10 at 18:01
    
I'm using student version of Win 7 Pro. There's no issue with licensing. All right, I'll just do without the bloody windows –  segfault Oct 9 '10 at 19:09
    
In this case there shouldn't be a problem getting it to work again. –  harrymc Oct 9 '10 at 19:59

Have you tried to boot from recovery disc?

yes, it says can't repair my computer, then I submitted the report to Microsoft, and it says checking for solution, but there isn't a known solution –  segfault Oct 9 '10 at 19:08
